pear more fully in the details hereinafter set forth, reference being had to the accompanying drawings, in which, Fig. 1 is an elevational view of a pair of hose clamps embodying Vmy `invention, operatively applied to a section of hose;

Fig. 2 is a sectional view taken on line 2-2 of Fig. l;

Fig. 3 is a transverse sectional view of one of my `hose clamps, certain parts being shown in elevati-on and disclosing the manner in A which my clamp is adapted to'be conveniently applied to and detached from a hose;

Fig. 4 is a fragmentary elevational View of the device, taken on line 4-4 of Fig. 3.

In the drawings, wherein similar characters of reference indicate corresponding parts in the several views of the preferred orm'of my invention, Y11 designates a metal Vstrap having a plurality of struck-out portions or apertures 12 arranged in spaced relation. To one of the ends of the strap 11 a small angle iron or plate 18 is secured by rivets 14, `the rivets also passing through a short section of metal stripping 15 underneath the strap 11,

the metal stripping serving to link the strap 11 with a second strap hereinafter described. The' angle plate 13 is provided with a projecting lug 16 having a hole 17 therein through which the threaded shank 18 of a 4.o thumb screw 19, havinga manipulating knob 20 formedintegrally with a cylindrical portion or barrel 21 which latter has a shoulder 22 seated against the lug 16,-is passed'. A. second strap 23 coacting with strap 11 is cut or formed at lone end toprovide a tongue i 24 on which the hook 25, formedy integrally with a small metal plate 26, riveted to strap 23, seats. The plate 26 is additionally se-V cured' to the strap 23 by thin strips of metal Y 27 on the margin of the strap 11 which border CLAMP 1929. VSerial No. 352,342.

the tongue 24. The; other end of the strap 23 Vis securedto the underneath thereof by rivets j 28', a second angleiron orplate 28 which is A provided with a pairot" hooks 29 arranged to provide a space 29 which 'accommodatesthe 5v5 l threaded shank 18, asvclearlyL shown in Fig. 1, the ends 30l of the hooks'29 beinglclenched to engage a nut 31 threaded von the shank 18 vof l the thumb screw...

The hose clamp hereinbeforedescribedis 60 particularlydesigned and `adapted to;withstand far more rough usage than conventional types of hose clamps, while providing a more convenient and expeditiousfmeans of securing a section of hose to any desired inlet or outlet. By inspection of Fig. 3- it will be seen that the 'strap 23 can be immediately lswung g Aat right angles to the shank 18 of thethumb screw 19, after which strap .11.is Aplaced over the hose B and4 then strap 23 ,n promptly L70 swung into the: Aposition shown4 ini'ull lines in Fig. 3. The strap 11 is -now presseddown to engage the hook25 infoneof the 4apertures 12, after which the'thumb screw isturned, thereby contracting'the ring formed Aby the 75 two straps joined by the hook25, it being observed that .the recessed' portion1f25 of hook 25 willl now receive the squareedge 12` at the bottom of theaperture 12. It will be observed that all parts vsusceptible oi break- `so age are not' vonly of extraV thickness Vof metal, such as theangle ironsr or platesl, 26' and 28, but litV will also rbe/ Inoticed that these elements-'are reinforcedby .the overlying and underlying straps' atV such a5' points where breakagewould be most `apt yto occur.j ,.'l`he hook V"25 has also been re-` inforced by.thepro`vision of Vthe tongue -24 f which latter, in addition, serves to distribute against the surface of the hose such pressure as might unduly be broughtto bear thereon by the hook if unsupported. Inthisrmanner the hose itself is guarded against a tendency vwto fracture .or puncture immediately `belowthe tongue24.-r' 1 i Y It will,'of course, be understood that the lin-l vention may be modified and changed without vdeparting from the spirit or` sacrificing I anyof the advantages of the device; and that the detailsoif lconstruction.l are 'not to be con-` 1,00

strued as confining the invention to the particular form illustrated, since it is my desire l `to avail myself of such changes and embodiments as fairly fall withink the scope of the appended' claims;

Having thus described my invention, what ,I claim as new'and desire to secure by Letters Patent is:

I l. A device ofthekinddescrbedcomprising.` a pair of straps, a pair of plates secured. to

l said straps, one of said plates having an aper-V tured portion receiving acoacting threaded Y member, the other of said plates having a pair of hooks loosely retaininga nut, saidfnut receiving said threaded member, one of said straps having ya plurality-of spacedv apertures formed therein and the other of said straps having a hook at onelend.

- 2. A hose clamp of the'kind described coml pris'ing a pair'of straps, one of said straps having a plurality of aperturesformed therein and a plate providedwith a lug having a s hole, the other ofsaid pair of strapshaving a hook at one end, and a pair, of hooks at the e other end arranged in spaced relation and adapted to loosely conine a nut held there: between, said lug having a hole receiving the "threaded: shank of an adjusting member, said Y shank being threadable in-said nut while a e0 shouldered `portion on said adjusting member-coacts with said lug. v

A hose clamp of the kind described comprising al pair of straps, one-of said straps hav-ingaplurality of holes therein arranged vins paced:relation andv adapted to be engaged by a hook lformed on a platejsecured to a second-strap coacting withl said irstrmentioned strap to form a hose engaging clamp, both of said straps having a pair of plates atan fend thereof, one of said pair of plates being provided with a hole receivinga threaded shankV on a manually operable member,

said shank being threadable ina nut non-rotatably yconinedbetween a pair of hooks in- FRED o. JOHNSON.

,tegrallyformed on another plate secured to the other osaid'straps whereby a shoulder on said manually operable member coacting with said lugyserves as a means by which said threaded `shank is adapted to compress or loosen said pair of.' straps to bind or release a 'hose therebetween.
